Deeper Tesla, Panasonic ties could lead to a Smart Home future

Published

on

A growing partnership between Tesla and Panasonic on solar cell production and storage batteries may one day eliminate residential reliance on the power grid and provide the capacity to recharge electric cars each night. However, to secure this collaboration on solar cell and module production, Tesla’s proposed SolarCity acquisition must first be approved by shareholders on November 17, 2016.  

In the meantime, Tesla and Panasonic have entered into a non-binding letter of intent under which they will begin collaborating on the manufacturing and production of photovoltaic (PV) cells and modules in Buffalo, New York. The Buffalo facility will become the largest solar panel factory in North America, with expectations to employ 1,460 workers and produce up to 10,000 panels per day.

A blog post on Tesla’s website acknowledged that the continued partnership with Panasonic is an important step in creating fully-integrated energy products for businesses, homeowners, and utilities and furthers Tesla’s mission toward a sustainable energy future.

The Relationship between Tesla and Panasonic

Tesla-Gigafactory-Roof-Drone-Flyover

The October 16, 2016 announcement confirmed that this newest collaboration extends the established relationship between Tesla and Panasonic, which includes the production of electric vehicle and grid storage battery cells at Tesla’s Gigafactory outside Sparks, Nevada. The $5 billion Gigafactory will produce batteries for the Model 3 electric car and energy storage products for home and utilities.

“We expect that the collaboration talks will lead to growth of the Tesla and Panasonic relationship,” said Shuuji Okayama, vice president of Panasonic’s Eco Solutions unit.

Battery cell production will begin by late 2016 and is expected to reach full capacity by 2018, producing more lithium ion batteries annually than were produced worldwide in 2013. In cooperation with Panasonic and other strategic partners, the Gigafactory will produce batteries that have the capacity to drive down the per kilowatt hour (kWh) cost of a battery pack by more than 30 percent. That anticipated cost drop is crucial, as current battery costs are untenable.

Panasonic plans to begin PV cell and module production at the Buffalo facility in 2017, and Tesla intends to provide a long-term purchase commitment for those cells from Panasonic. The Tesla/ Panasonic collaboration could mean that energy from solar panels will be pumped into home storage batteries. No longer would residential home solar systems follow the traditional model of selling back to utilities.

Panasonic’s Future Home

The proposed Tesla/ Panasonic collaboration would shift Panasonic’s historic focus from consumer electronics products and onto housing, automotive information systems, and vehicle batteries, which “would be a win” for Panasonic, according to Bloomberg. Panasonic’s transition to the home electric market began in 2009 with its Tokyo Future Home, which features the latest environmental technologies and a few prototypes. The house is designed to aid natural ventilation and cut down on air conditioning. The walls of the house are lined with a thin and efficient insulator that cuts down on heating and cooling costs. LED lights, which use much less power than incandescent bulbs and last longer than current fluorescent models, are sensor-controlled. Extra generated electricity is stored in a prototype accumulator battery of lithium ion cells for later use. The lights, power, heating, and other apps are controlled in a high-tech in-house network with living room TV at the center.  

The aim of Panasonic’s energy-saving house is to be carbon neutral in energy usage.

Tesla’s Smart House Could Utilize Panasonic’s Technology

Tesla is currently developing advanced systems that adapt to the needs of the environment with the goal is to bring top quality affordable systems that provide energy efficiency, quality of life, and home security.

Already, smart home system are able to cut electric energy spending by 50%, or in some cases go off-grid using Tesla batteries combined with solar. Lights, air conditioning, and all other appliances are automatically managed, turning on and off, depending on the time of day, temperature, motion sensors, door and window detectors, and electricity rates. Fingerprint scanner and pin lock, video surveillance, night vision camera, motion sensors, SMS alarms, fire and flood sensors are accessed through a phone.

In 2014, Panasonic opened a smart city near Tokyo that is designed to drastically cut CO2 emissions by 70%, reaching to 1990 levels. It will attempt to reduce water usage by 30 percent and achieve 30 percent renewable energy usage. Called the Fujisawa Sustainable Smart Town (SST), the subdivision southwest of Tokyo focuses on solar power and other environmentally friendly technologies.

Together, Tesla and Panasonic may be able to ground ambitious plans for solar-powered systems that charge smart homes and electric cars and make decentralized renewable energy systems that power homes and car a practical reality. “We are excited to expand our partnership with Panasonic as we move towards a combined Tesla and SolarCity,” JB Straubel, Tesla’s chief technical officer and co-founder, said in a statement. “By working together on solar, we will be able to accelerate production of high-efficiency, extremely reliable solar cells and modules at the best cost.”

The Role of the Projected SolarCity Acquisition

The Tesla/ Panasonic collaboration moving forward is contingent on Tesla’s acquisition of SolarCity, but shareholders must approve the move. Tesla’s bid to acquire SolarCity has been fraught with corporate governance issues because the boards of both companies are deeply intertwined.

Tesla co-founder Elon Musk’s effort to unite Tesla and SolarCity has been under close scrutiny, given six of the seven directors on Tesla’s board have SolarCity ties and SolarCity’s CEO, Lyndon Rive, is Musk’s first cousin.

SolarCity, among the top installers of residential rooftop solar panels in the U.S., acquired solar manufacturer Silevo in 2014. The transaction gave SolarCity the factory in Buffalo where Panasonic will begin photovoltaic cell and module production. If the SolarCity acquisition is successful, Tesla will use the cells and modules in a solar energy system that will work seamlessly with Powerwall and Powerpack, Tesla’s energy storage products. With the aid of installation, sales, and financing capabilities from SolarCity, Tesla will bring an integrated sustainable energy solution to residential, commercial, and grid-scale customers.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones

Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.

Published

By

Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”

He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”

That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.

SpaceX pitches subscription model for Trump’s Golden Dome

While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.

The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

Tesla opens the Q&A for its biggest earnings call yet

Tesla opens its Q3 earnings Q&A, and Cybercab, Robotaxi, Optimus and regulators loom over October 21.

Published

Tesla has opened its shareholder question portal for the Q3 2026 earnings call, with the Say Q&A page already listing questions. Investors have until 4:00 p.m. EDT on October 20 to submit and vote on what management should answer.

The call is set for Wednesday, October 21. Tesla will post results after the market closes, with a live webcast at 4:30 p.m. CT, or 5:30 p.m. ET, through its investor relations site.

Say ranks questions by the number of shares behind the votes, which gives institutional holders extra weight over the retail crowd.

Ahead of Q2, retail investors asked why Robotaxi growth had stalled, when Cybercab would start customer rides, and where the Optimus Gen 3 ramp stood, while an institutional holder asked how Tesla and SpaceX would split Terafab duties. Cybercab has since answered one of those. Tesla said last week it has 300 plus Cybercabs serving Austin, up eightfold in 30 days, with Dallas named as the next city. The questions now are likely to move from when to how fast.

There is also a regulatory question hanging over the call. NHTSA has demanded sworn answers on how the pedal free Cybercab was certified against federal safety standards, with responses due October 30, nine days after the call. Whether an analyst raises it live is unknown, but it is the kind of exposure that tends to find its way into a Q&A.

The numbers will not be the main draw. Tesla already reported 486,532 deliveries and 13.7 GWh of storage for the quarter. Consensus sits around 43 to 45 cents per share on roughly $27.8 billion in revenue, according to Zacks, after a Q2 report that missed on EPS. Goldman Sachs, which holds a Neutral rating and a $360 target, argues the outlook for Robotaxi, FSD and Optimus will matter more to the stock than the quarter itself.

The call also lands six days after the rescheduled Roadster event, which Tesla will stream on X on Thursday, October 15, at 7:55 p.m. CT. If the Roadster shows up with a production date or a SpaceX thruster package, expect it to climb the voting list before the deadline.

FAA kicks off review of SpaceX’s bid to fly Starship nearly every day

FAA is reviewing SpaceX’s plan for 456 Starship launches a year, up from 25 today.

The FAA said Tuesday that it will prepare an environmental impact statement on SpaceX’s proposal to run as many as 456 Starship launches and 912 landings a year from Starbase, Texas. SpaceX is currently authorized for 25 launches and 50 landings annually, which makes the request roughly 18 times the existing ceiling. The notice of intent is set to publish in the Federal Register on Wednesday.

The plan comes in two phases. Phase 1 would allow up to 100 launches and 200 landings a year, on any day and at any hour. Phase 2, which the FAA says could arrive within several years, would raise the limit to the full 456 launches, still at any hour but only on weekdays. The agency noted that 912 landings is the upper limit for the Texas facility no matter where a given mission begins, and that Starship and Super Heavy could come down at the launch site or in the Gulf and open ocean.

A draft statement will be released for public comment at a later date, and the FAA has not said when. According to the Federal Registar, written comments are due November 30 on regulations.gov under docket FAA-2026-12808, with in person scoping meetings on November 17 in Brownsville and November 19 in Port Isabel, plus a virtual session on November 18. The review will weigh air quality, wildlife, coastal resources, water, noise, and aviation, and the FAA said any increase beyond this proposal would need its own separate review.

The numbers look large next to what Starbase has actually done. Starship has flown three times from Texas this year, including Flight 14 on September 28, the first orbital flight, which deployed 26 Starlink V3 satellites. Bloomberg reported that Starbase has never launched more than five times in a calendar year. The current cap of 25 comes from an FAA approval in May 2025. In February, the agency also approved up to 44 Starship launches a year from Launch Complex 39A in Florida, so Phase 1 in Texas alone would more than double that allowance.

Musk has said Starship could eventually fly more than once per hour within less than a decade, per Bloomberg. The nearer term target is Flight 15. Musk said on October 10 that it is hopefully four to six weeks away and will try to catch the ship with the tower, as Teslarati covered. That flight still runs under the existing 25 launch limit, and so would every Starbase launch for as long as the new review takes.
